ABRAHAM N. WOLF, Or MILL CREEK TOWNSHIP, AND JOEL HAAG, OF .BERNVILLEPENNSYLVANIA.

Letters Patent No. 94,162, dated Aug'ust24, 1869.

The Schedule referred to n these Letters Patent and making part of thesame. y

To all whom it may concern:

Beit known that we, ABRAHAM N. WOLF, of Mill Creek township, in thecounty of Lebanon, and JOEL HAAG, of Bernvillc, in the county of Berks,and' State of Pennsylvania, have invented certain new and useJ fulImprovements in Turbine-Centre and Lower-Discharge W'ater-lVheels; andwe do hereby declare that the following is a full, clear, aud exactdescription thereof, reference being had to the accompanying drawings,and to the letters ofreference marked thereon, whiclrform a part of thisspecification, in which- Figure 1 is a central vertical section of' ourwheel.

Also, in the combination and general arrangement of the partshereinafter mentioned A, in the annexed drawings, represents a plan viewof the upper casing of the wheel.; also the position andform of thevalves'G;

D represents the guards; and

B the gates.

The guards D are formed so as to curve inward at theirouter end, andconfined in position by' screwholts.

The gates B are pivoted at their lower end by-means of a bolt, so as toadmit of its opening and closing the chute, through which the waterreaches the buckets d.

The mode of rendering thesaid gate adjustable will be hereinafterdescribed.

C designates a concai-'o-convex valve, hinged to the outer end of gateB; its olice being to prevent the water entering between the guard D andthe gate B.

E represents a grooved-wheel, secured to the surface of casing A.

Y 'g g are metal rods, the inner ends of which enter the vgroove inwheel E. and are there fastened with a bolt.

The outer ends of rods g g pass through a slide, marked h,- the saidslides being placed directly over a slot cut in the rim or casingA, andhaving a screw` bolt passing through them, through the slot, and intothegate B.

As the outer end of each rod g is formedinto a screw, and is furnishedwith a nut on each side of slide h, by operatingI said nuts, it will beseen that the slide h and the gate B, to which the slide is fastened,will move outward or inward, as required, and either diminish or enlargethe Opening' in the chute.

It will be observed that the slides h h are operated simultaneously bymeans of the spur-wheel en, which gears into vthe cogged bar a; the saidIcogged bar u being rigidly `confined to the 'surface of grooved wheel'H' designates a box, embracing the shait j of the water-wheel F; thesaid box being designed asan oilchamber, from which oil will eXude tolubricate the step, on which the vshaft rests.

The water-wheelF revolvesinside of casing A, and

is furnished with buckets of a convexo-concave form.l

Having thus'described our invention,.

What we claim, and desire to secure by Letters Patent, is i 1. Thevalves C C, in combination with gates B B, operatingtogether,substantially as and for the purpose described.

2. The combination, substantially as set forth, of guards D D, valves CC, and gates B B.

3. The slides h h, in combination with valves G C,
